| The advantages and production process of hot push elbow machine
Hot push elbow technology that is the advantage of medium frequency heating elbow machine: hot push elbow wall thickness unchanged.
According to the expansion and flow laws of metal materials, the translation of the bending neutral layer to the outer arc and the non-plastic deformation of the outer arc of the elbow are realized by the theoretical calculation and the medium frequency induction heating pushing process, so that the wall thickness of the elbow is not thinned during the bending process.Namely, after bending the elbow, the wall thickness of the outer belly and the inner belly is uniform, which avoids the uneven wall thickness phenomenon of the inner side thickening and the outer side thinning during the deformation of the traditional bending process.Intermediate frequency bend machine belong to the non-standard products, there is no specific limit specifications, can according to customers' special requirements directly, Mr Cheng machinery co., LTD. Not only the production of bend machine, intermediate frequency bend machine drive system, and intermediate frequency pipe bending machine, cold extrusion machine, cold drawing tee thermoforming pipe-expanding machine and other mechanical equipment, equipment can meet the domestic and foreign market demand.
Classification of intermediate frequency elbow machine:
1 medium frequency elbow machine to produce carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon crutch, PVC, PPR, RFPP(reinforced polypropylene) and so on.
2. According to the key points of production, it can be divided into push, suppress, forging, casting, etc.
3. In terms of manufacturing scale, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.
4. Medium frequency elbow machine production elbow according to its radius of curvature to divide: can be divided into long radius elbow and short radius elbow.Long radius elbow refers to its radius of curvature which is 1.5 times the outside diameter of the pipe, i.e. R=1.5D.The short radius elbow refers to its radius of curvature, which is the outside diameter of the pipe, i.e. R=1.0D.(D is the elbow diameter and R is the radius of curvature).
5. According to the pressure grade: there are about 17 kinds, and the United States pipe size is the same, there are: SCH5S, SCH10S, SCH10, SCH20, SCH30, SCH40S, STD, SCH40, SCH60, SCH80s, XS;SCH80, SCH100, SCH120, SCH140, SCH160, XXS;The most common ones are STD and XS.
